Internal wiring for DIY amp?

Recommended Posts

I am working on putting together the parts for my upcoming TPA3255 amp build and was wondering what you guys use for internal wiring? Specifically, the AC power from the plug to the PSU, the DC power from the PSU to the amp, the line level wiring then the final output wiring? Thanks in advance for the advice.

Use appropriate voltage and current rated wire for the internal AC and DC. All twisted pairs. IEC inlet with solid ground connection to the enclosure. All exposed metal parts must have continuity to that ground connection. Small signal can be cat5 etc or tephlon covered silver 22-24 gauge or anything fancy like that. The speaker output can be anything. Oxygen free copper speaker wire will work.
